Application Ied November 20, 1919.

To all whom t may concern:

Be it known that I, CLYDE MACCANN CARP., a citizen of the United States, residing at Fort Scott, in the county of Bourbon and State of Kansas, have invented a new `and practical Railroad-Switch Stand, of

which the following is a specification.

The object of this invention is,

l. To move the switch points and to hold the same firmly against the rails.

2. To provide a switch stand capable of having working parts incased to protect same from snow, rain, etc.

3. To provide ease of operation and less fatigue to the operator.

The figure of the drawing shows the switch stand in vertical section.

The following is a clear and concise description of the switch-stand. The principal working parts are, hand lever D, cogwheel A, cog B, threaded shaft C and square shaft F which is connectedto the rails by a connecting rod of any description. Cog wheel A is l0 inches in diameter, and cog wheel B is one inch in diameter, moving hand lever D approximately 1800 from normal position (which is horizontal) causes cog wheel A to turn, which causes cog B to make five revolutions, throwing threaded shaft C and Specification of Letters Patent.

square shaft F backward or forward,

opening or closing the switch as the case may be. Cog Gr also turns the target E.

Having described my invention what I claim is,

l. In a railway switch stand, the combination of a connecting rod, one end of which is attached to the switch, the other end being of round cross section, and threaded, a round nut upon the threaded end, provided with a toothed gear by which it can be rotated to impart lateral motion to the switch rod, a `second toothed gear inter-meshing with the rst, and secured upon an operating shaft, journaled on the switch stand, a lever attached to one end of said shaft for rotating the same, a beveled gear wheel upon the other end of said shaft, and a second beveled gear wheel inter-meshing with the first, and arranged to rotate'a switch signal.

2. A switch stand as set forth in claim l, in which the working parts are protected from the weather by a suitable housing or l casing.

3. A switch stand as set forth in claim 2, in which that part of the connecting rod passing through the housing is of square cross section to prevent its rotation.
